Nice pics, thanks for posting ! I think those are 4X4 Slash rims but in black rather than silver ? I like.

I have a Lightning Stadium 10, pretty much the same as CRT.5 and I myself have heat issues with the 4600. I bought a 2700kv 5mm shaft 50mm motor from HobbyCity and it runs very well (110degrees) on 3s.
I really like the Hyper SC but I'm leaning more torwards the 4X4 Slash for several reasons, Durability,weight,parts availibilty,cheaper in the long run and will run on 2s.
I bought (3) 2s 30C 5000mah packs from Hobby City deleivered for under $100.00, taht just can't be beat !
I beleive due to the weight of the Hyper SC 3s will be nessasary.
